Siemens SIRIUS 3RU2 Thermal Overload Relay Stand Alone Mount 1 NO/1 NC 1.25A FLC 3A Contact Current 750W 690V AC 3RU2116-0KB1

Siemens 3RU2116-0KB1 SIRIUS 3RU2 thermal overload relay is a robust, stand alone mount device designed for current-sensitive protection of motor loads with normal starting characteristics. It features a 1 NO/1 NC contact configuration, making it suitable for control and protection circuits requiring precise overload sensing.

This relay supports motors with a full load current rating of 1.25A and relay contact current capability of 3A, with a power rating of 750W and a supply voltage rating up to 690 volts AC, suitable for a wide range of industrial applications.

The device includes two auxiliary contacts and uses screw terminals for secure wiring connections. Its adjustable current range from 0.9 to 1.25 amperes provides flexibility for fine-tuned overload protection. Reset methods include both automatic and manual options, allowing adaptability in different operating environments.

Designed to operate reliably in ambient temperatures ranging from -40°C to 70°C, this relay is rated IP20 for protection against solid objects, making it suitable for indoor industrial environments. It complies with major international standards including UL, IEC 60529, IEC 81346-2, IEC 60068-2-27, and CSA, ensuring safety and performance.

The compact form factor with dimensions 80mm wide, 45mm long, and 89mm deep facilitates easy installation in control panels or machinery.

Common applications include use in industrial machinery control, automation systems, HVAC motors, manufacturing plants, and other commercial or industrial electrical installations requiring reliable and precise overload protection.

Package contents include the thermal Overload Relay unit with integral indicators such as a switch position indicator and test function, a stop button, and a selector switch for manual or automatic reset operations. Mounting options include surface or DIN rail configurations compatible with Siemens Sirius contactors size S0 and S00. Screw terminals are exclusively compatible with corresponding screw terminal overloads, while spring terminals must be used with spring terminal overload variants.
